Answer: Getting into the technicalities, the continental crust has a density of around 3.0 g/cm3 compared to 2.6 g/cm3 of the continental crust. In addition, the continental crust is much thicker than the oceanic crust.

A catalyst is something that is used to lower the activation energy of a reaction, that is later regenerated by the reaction (but the equilibrium isn't altered). In this case, an enzyme is an organic (protein) catalyst, so that's your answer.
Bones are made up of a framework of a protein called collagen , with a mineral called calcium phosphate that makes the framework hard and strong.
The negative impact of chemistry have on society through the production and use of chlorofluorocarbons (CFCs) is that lower levels of ozone allowed more ultraviolet radiation to reach Earth. CFC is an organic compound which is used refrigerants, propellants and solvents.
Answer:
6.85 g
Explanation:
Step 1: Given data
- Molar concentration of the solution: 0.200 M (0.200 mol/L)
- Volume of the solution: 100.00 mL (0.10000 L)
Step 2: Calculate the moles of sucrose (solute) required
Molarity is equal to the moles of solute divided by the liters of solution.
M = moles of solute / liters of solution
moles of solute = M × liters of solution
moles of solute = 0.200 mol/L × 0.10000 L = 0.0200 mol
Step 3: Calculate the mass corresponding to 0.0200 moles of sucrose
The molar mass of sucrose is 342.3 g/mol.
0.0200 mol × 342.3 g/mol = 6.85 g
